Pallade Veneta - 'Little hope' of saving beluga whale stranded in Seine river

The whale was first spotted on Tuesday in the river that runs through Paris to the English Channel. Since Friday it has been between two locks some 70 kilometres (44 miles) north of the French capital.

But leaving it in the warm stagnant water between the lock gates is no longer an option.

"He has to be moved in the coming 24-48 hours, these conditions are not good for him," Sea Shepherd France head Lamya Essemlali told AFP.

Specialists held out "little hope" for the visibly underweight whale, Essemlali said.

"We are all doubtful about its own ability to return to the sea," she said. "Even if we 'drove' it with a boat, that would be extremely dangerous, if not impossible".

However, "the euthanasia option has been ruled out for the moment, because at this stage it would be premature," she said.

The whale still has "energy ... turns its head, reacts to stimuli", she said after a meeting of experts and French officials.

Although rescuers have tried feeding it frozen herring and then live trout, the animal was refusing the food.

"His lack of appetite is surely a symptom of something else... an illness. He is malnourished and this dates back weeks, if not months. He was no longer eating at sea," Essemlali said.

Small spots that were reported on its pale skin on Saturday were likely due to the fresh water, Sea Shepherd said.

Another option under consideration would be to take it out of the water, give it vitamins, check the cause of the illness and ship it out to sea to feed.

- Rare sighting -

Belugas are normally found only in cold Arctic waters, and while they migrate south in the autumn to feed as ice forms, they rarely venture so far.

An adult can reach up to four metres (13 feet) in length.

According to France's Pelagis Observatory, specialised in sea mammals, the nearest beluga population is off the Svalbard archipelago, north of Norway, 3,000 kilometres (1,800 miles) from the Seine.

It is only the second recorded sighting of a beluga in a French river since 1948, when a fisherman in the estuary of the Loire river found one in his nets.

The sighting comes just a few months after a killer whale -- also known as an orca, but technically part of the dolphin family -- became stranded in the Seine and was later found dead between Le Havre and Rouen in late May.

Officials said they had also discovered a bullet lodged in the base of its skull -- though it was far from clear that the wound played a role in its death.
